Abstract

The utility model relates to an industrialized scale economy type photo bioreactor. The main body of the reactor is a flat plate stand type frame made of metal; a welded net is attached on four walls in the frame; plastics is laid in the welded net; an air supply pipe is longitudinally laid in the plastics; breathing holes penetrate through and are drilled on the air supply pipe; a breathing pipe is fixed at the bottom part of the reactor through a upright column; floor leather or other smooth material is matted under the plastics. The photosynthetic bioreactor adopts flat plate vertical box type design, the common transparent plastics is taken as the main body to replace glass, specific high pressure glass, and steel stainless material, and the material cost is greatly reduced; the flat plate vertical box type design can enlarge area volume ratio and improve illumination absorption efficiency and light energy conversion efficiency of cells; the photo bioreactor is transversally communicated and can be infinitely extended, and thereby the obstinate illness that the amplification of the bioreactor is difficult is solved; the breathing pipe is laid at the bottom part of the reactor in the new design, in order that algae cells can achieve very good floating in the reactor.

Description

The economical bioreactor of industrially scalable

Technical field

The utility model relates to the economical bioreactor of a kind of industrially scalable.

Background technology

At present, global increased population is ploughed and is reduced, and grain and feed shortage are more and more serious.Algae belongs to lower plant, and it is the fastest to grow, and the useful output ratio is the highest, and yield per unit the highest (can reach 15 tons of dry powder of per mu yield) is to solve grain and the most promising field of feed shortage.Algae is a large amount of to be cultivated except in the huge prospect aspect grain, the bait, and at medicine, also there is good prospect aspects such as cosmetics additive.As algae anticancer radiation-resistant ability of enhancing is arranged; Algae contains abundant biologically active substance, as arachidonic acid, and microbiotic, carotenoid, vitamin-E, long-chain unsaturated fatty acid (as DHA, EPA etc.), SOD (superoxide dismutase) etc.; With the algae is material, but by genetically engineered and inducing culture enrichment SOD, the yield of the fresh algae mud of every 1kg Fe-SOD is 0.3～0.5g, can produce huge economic benefit; Can be used as the fluorescent probe of diagnostic kit from the phycobiliprotein of algae separation, extraction, purifying gained.Algae is the treasure-house that enriches of natural product, therefrom can extract biochrome astaxanthin, phycobiliprotein, chlorophyll, xenthophylls, carotene, the oxidation-resistance of astaxanthin is higher 500 times than VITAMIN, can be widely used in pharmacy industry, and is the additive of foods and cosmetics.Little algae also is the natural openings bait of aquatic animal fish, shrimp, crab, shellfish, as many Clupeiformes, mullet type order fish and numerous shrimp crab class young, all being rich in diatom from ingesting makes a living, the mud snail that creeps on the seabeach, the various snails of crawling on the cay, what they licked is exactly the diatoms that dwells at the end.Chlorella, Chaetoceros, salt algae etc. all are the open-mouthed baits of scallop, abalone, sea cucumber etc.Because this slightly algae be rich in EPA and DHA, as the open-mouthed baits of the aquatic animal young such as prawn, scallop, abalone to the surviving rate that improves the young with build up health and play an important role.

Little algae still is important industry and energy raw material simultaneously, and chlorophyll can be for the usefulness of making reodorant and hematinic and food dyeing.Past mainly extracts from clover, because content has only 0.2%, so cost is higher, and the content of Chlorococcum allochlorophyll generally reaches 4-6%, surpasses content 20-30 times of clover, if extract chlorophyll with this algae, can reduce cost greatly.Unicell green alga class and diatoms all contain abundant β-Hu Luobusu, and this pigment is a provitamin A, can propose to use for the system medical material.Astaxanthin belongs to carotenoid, is Crustacean, as the main pigment of shrimp, crab and salmon.The astaxanthin price of synthetic is very expensive, in the process of synthetic, may be polluted by other objectionable impurities, also contain non-natural isomer in the product, and therefore the content astaxanthin of blood cell algae has broad prospects with the source of blood cell algae as production of astaxanthin industry far above the production source of other natural astaxanthins.Chlorella is under suitable culture, can improve content of oil and grease in the cell, the salt algae is under suitable salt concn, its glycerol content can reach 50% of dry weight, sterol content in the green algae is also higher, and cartilage chrysanthemum sterol is arranged in sterol, is the good material of synthetic Kendall compound, this shows that these algae are the fine raw materials that extract grease, sterol etc.Some algae then can be used for production sustainable use energy ethanol and hydrogen.

Little algae also is used as farmland fertilizer sometimes, because most of blue-green algae has the biological nitrogen fixation ability, and can be at a large amount of nomadic nitrogens of soil internal fixing, supply with nitrogenous fertilizer, can improve the fertile degree of paddy soil because blue-green algae be unique have by photosynthesis produce oxygen, have the biology of nitrogen fixing capacity again.

The little algae of little algae and transgenosis also has application and good prospect widely in wastewater treatment and environment protection industry.Thread spirulina, anabena ratio are easier to separate from nutrient solution, thereby are to be used for the up-and-coming little algae of wastewater treatment.With various organic sewages or nitrogenous, phosphorus sewage cultivation spirulina, sewage is purified, reduce environmental pollution, the algae biomass that obtains can also be used as feed, fertilizer, even can be used for producing useful chemical substance.Compare with traditional tertiary treatment, use the spirulina process for the treatment of waste water, have that cost is low, power consumption is few, benefit is big, and the characteristics of non-secondary pollution are environment-friendly engineerings that potentiality to be exploited is arranged very much.

If these achievements can be applied to produce, offer convenience for people's life and produce huge economic benefit.The efficient photosynthetic organism reactor assembly of our development can be used for seawater or fresh water algae are carried out high-density, high-purity large-scale industrialization sealing cultivation.

Utility model content technical problem to be solved in the utility model is, provides a kind of industrially scalable economical bioreactor, be suitable for little algae large-scale industrial production and use, and at a low price, efficient.

The technical solution of the utility model is as follows:

The economical bioreactor of a kind of industrially scalable is characterized in that: reactor body is made of metal dull and stereotyped stand-type framework; Wall is pasted with the weldering net in the framework; Be equipped with plastics in the weldering net; Vertically be equipped with air-supply duct in the plastics; Connect total length on the air-supply duct and be drilled with ventilating pit; Ventpipe is fixed on reactor bottom by column; Place mat flooring laminate or other lubricious material under the plastic bottom.

Positively effect of the present utility model is: this photosynthetic organism reactor adopts flat board box design of standing to make main body by common light-passing plastic and replace glass, extraordinary high-pressure glass and stainless material, greatly reduces material cost; And the flat board box design of standing can increase area-volume ratio, improves the conversion of solar energy of illumination assimilated efficiency and cell; New design cross connection can infinitely prolong, and amplifies difficult chronic illness thereby solved bio-reactor; New design is laid ventpipe at reactor bottom, makes alga cells can reach fine suspension in reactor.
